Consider a distributed storage system with

20

racks, each containing

15

servers, and a

network bandwidth of

512

Mbps

.

The system employs the Rack Awareness algorithm for fault tolerance. If there are

30

GB of data to be distributed and each block should be replicated across

5

racks, how many copies of each data block will be stored in total across the entire system? If

4

racks experience network issues causing delays in accessing data stored on them, what is the probability that a randomly chosen data block can still be accessed without relying on the problematic racks?
